How Long Do Fleas Live Without a Host?

The life cycle of fleas is a complex one that includes several stages. It can last anywhere from a few days to a few weeks, depending on the species and environmental conditions. Fleas can survive for a few weeks without a host, but without a blood meal, their numbers would quickly dwindle. After feeding on a mammal’s blood, a female flea will lay up to eight eggs on its host’s fur. These eggs are non-sticky and require a warm environment in order to survive. Without a host, the eggs will die.

Flea pupae are capable of detecting potential hosts, such as the warmth of a human body or the presence of carbon dioxide. When they sense these factors, they emerge from their cocoon and start looking for a new host. Once they find a suitable host, they will breed and lay eggs.

Flea larvae lay their eggs in a pet’s fur. Their eyes are primitive, so they rely on their senses to find a host. Flea larvae are also attracted to light and heat. This means they prefer bright light to dark places.

Fleas are not able to fly. They use their hind legs to jump on hosts. A flea can jump up to eight inches.
